Declination
Date 2019-10-14
Latitude 28° 13' 30" N
Longitude 110° 20' 45" W
Elevation 0.0 km GPS
Model Used WMM2015V2
Declination 8° 55' E changing by
0° 6' W per year
Compass shows the magnetic bearing of the
Uncertainty 0° 19' magnetic north (MN)
Magnetic declination is the angle between true north and the horizontal trace of the
local magnetic field. In general, the present day field models such as the IGRF and
World Magnetic Model (WMM) are accurate to within 30 minutes of arc for the
declination. However, local anomalies exceeding 10 degrees, although rare, do exist.
